METALLIC RAILWAY-TIE.

Application filed October 22, 1917. Serial No. 197,873.

To all whom it may concern Be it known that I, MIQHAL Kwrnr- KOWSKI, a subject of the Emperor of Austria, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Metallic Railway-Ties, of which the following is a specification.

This invention relates to certain new and useful improvements in metallic railway ties.

The primary object of the invention is the provision of a railway tie which possesses great strength and maybe easily and cheaply manufactured, the same also being light in weight.

A further object of the device is the manner of forming a railway tie from a single piece of sheet metal, the only additional elements being employed being screwing means for the overlapped portions thereof when assembled in tie formation.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout theseveral views,

Figure 1 is a plan view of the blank from which the tie is formed.

Fig. 2 is a side elevation of the tie with an end portion thereof broken away.

Fig. 3 is a top plan view of an end portion of the tie.

Fig. 4 is a transverse sectional view taken upon line IV-JVof Fig. 2, and

Fig. 5 is a perspective view of an end portion of the tie when only partially formed.

Referring more in detail to the drawing, a blank 10 of sheet metal is provided substantially rectangular in form, the same being adaptedfor folding upon parallel lines 11 to form overlapping bottom sections 12 for the tie.

Opposite three-sided projections 13 are formed at the ends of the blank 10 while parallel slits 14 are cut through each extension corresponding with bends 15 in the metal blank providing the top sections 16 of the tie therebetween. The sections 17 of the metal positioned between the bending lines 11 and 15 constitute the sides of the tie while bending lines 18 are arranged between the ends 19 of the extensions 13 and opposite points as 20 of the top wall 16 and providing substantially triangular-shaped overlapping'fiaps 21.

With the blank formed as shown in Fig.

Specification of Letters Patent.

Patented June 1, the same is bent upon the lines 11 and 15 for bringing the sections 12 in overlapping relations for securing the same together by means of rivets 22p1aced through perforations 23 in the said bottom sections. This arrangement of the bottom sections 12 brings the top section 16 in parallelism therewith with the side sections 17 obliquely connecting the said top and bottom sections together. The end flaps 21 are then folded inwardly upon the lines 18 and overlapped for bringing the perforations 24 of the flaps in alinement with each other while the adjacent tongues 25 formed by means of the slits 14 overlies the flaps 21 with its perforations 26 in alinement with the perforations 24 adapted for the reception of a rivet 27 securing the said flaps and tongues permanently together.

The forming of a straight end portion 28 for each extension 13 having obliquely cut edges 29 between the ends of the edges 28 and the points 19 of the blank furnishes a small triangular opening 30 at the end of the tie adapted for the reception of an implement, not shown, for positioning the rivets v27 during the assembling of the tie. The edges 29 of the extensions 13 are in alinement with the end edges of the bottom sections 12 when the device is assembled while the adjacent edges 28 thereof will be arranged oblique to the end edges of the bottom sections 12 upon the overlapping of the flaps 21, thus forming the opening 30 as set forth. Suitable brackets, not shown, for

mounting the rails transversely upon the top 16 of the tie are adapted to be secured thereto by means of perforations 32 in said top section 16. The openings 30 also permit any moisture to pass out of the tie upon the roadbed and it will be seen that on account of the tie being hollow, the same is light in weight While being formed from sheet metal, the same possesses great strength and durability. 4

What I claim as new is 1. A hollow single piece tie comprising a piece of sheet metal substantially rectangular in form having opposite longitudinal marginal sections adapted for overlapping forming the bottom of the tie when the blank is folded with a middle section forming the sash top thereof and intermediate sections format the ends of the blank forming tongues as continuations of the top section of the tie and" further forming opposite substantially rectangular portions adapted for overlap-- ping each other beneath the said tongues and therewitli forming oppositely sloping ends for the tie, hold-fast devices for the tongues and fiaps and hold-fast devices for the bottom sections.-

I 2. A metallic sheet metal tie comprising a substantially truncated pyramid shapehaving overlapping bottom sections, overlap ping inturned flaps at the ends of the tie, tongues at the'opposite ends of the tie overlappingthesaid flaps and hold-fast devices between the saidfiaps andtongues, the said Copiesof this patentmay be obtained for fiver cents flaps being arranged relatively to the bottom sections in such a manner as to form openings at the opposite ends of the tie.

3. A sheet metal tie having overlapping bottomsections and a relatively narrow top section parallel therewith, inclined side sections connecting the said top and bottom sections having severed end portions forming opposite flaps and intermediate tongues adapted for overlapping the said flaps and hold-fast devices between the said tongues and flaps whenthe saidmembers are in their end forming arrangement for the-tie.

In testimony whereof I afliX my signature.
